IMPROVED APPARATUS FOR CAR B URETlNG AIR.

Specification forming part of Letters Patent No. 46,280, dated February7, 1865.

Auburndale, in the county of Middlesex and- State of Massachusetts, havemade a new and useful or Improved Apparatus for vaporizingan-d,'Ae1-ating a Volatile Hydrocarbon; and

I -do hereby declare the same to be fully described in the followingspecification and represented in the accompanying drawings, of which-Figurel is a top view, and Fig. 2 a side elevation, of it. Figs..3 and 4are transverse and vertical sections of the vaporizer, one being takenin a plane at right angles to that of the other. Fig. 5 is a verticalsection of the air-forcing apparatus, such section being taken in lineof the axis of the shaft of such apparatus. Fig. 6 is a top view of theairforcing apparatus with its bell-cover removed from its cistern. Fig.7 is a transverse section of such air-forcing apparatus, taken throughone of its air cases or cells.

In constructing my apparatus for carbureting air or vaporizing andaerating a volatile hydrocarbon, I employ two cisterns; A B, each havinga bell-cover, O, dipping into an annular trough, a, forholding water.Within the first of the cisternsviz that marked A- I arrange twoinverted air cells or cases, D E, each of which is open at bottom. Thelower edges of these cases are to be on a level with each other, and on.or about on a horizontal shaft, F, which goes through the cistern.

These cases projectin opposite directions from the said shaft. Withineach ofthe cases I) E there is a bucket or air scroop, G, the same beingmade to project (mouth downward) from the shaft and so as to rotate orvibrate with it. These scoops extend in opposite directions from theshaft. There is an air passage or hole, H, opening out of each air-caseand made through the side of the cistern A, such hole being arranged ata level above that at which water is to stand in the cistern, such levelbe ing a little above the shaft F. From the same it will be seen that ifa reciprocating vibratory motion be imparted to the shaft F, so as tocause the buckets or scoops to be alternately raised out of the waterandinto the air of their cells, the buckets will receive air and carryit down into the water, and when each bucket may have been moved belowthe surface of the water more than ninety degrees of'a circle the airwill escape from the bucket into the water and pass up through thelatter and into that part of the cistern which is above the water,

From the air-space ot' the cistern A a. pipe, I, extends and passes intothe cistern B, and opensinto the head of an agitator andair-distributor, K, which is arranged within the lower part of thecistern B, and in its construction is like the well-known Barkerscentrifugal mill that is to say, it consists ofa hollow hub, b, providedwith aseries of tubular arms, 00 c c, which are perforated with holes,so arranged that while air may be ejected from them into a liquidsurrounding them such air will operate to put the agitator in rotationwithin the liquid. The hub may be perforated with holes for ejecting the.air in the proper directions to aid in effecting the rotation of theagitator. ()n the top of the hollow shaft of the agitator them isbevelgear, d, which engages with another such gear, 0', fixed on ahorizontal shaft, f, which not only goes through and out ofthe cisternB, but has a series of arms, ggg, &c., extended from it. To each ofthese arms one or more pieces of sponge, /1, or other suitableabsorbeutmaterial, should be affixed. The hydrocarbon fluid to be vaporizedandaerated or mixed with air, is to be placed in the cistern l3, and soas to cover the agitator or distributer K, and extend nearly, if notquite, up to the shaft f. The air from the air-forcing apparatus of thecistern A being blown through the pipe I into the distributor K will beejected from the orifices thereof directly into the hydrocarbon fluid,and by its action, against such fluid the air will cause the distributorto revolve thereon. The rcvolutionof the distributor will not only moreor less agitate the liquid, but will cause the air to be very thoroughlydistributed in the liquid, and so as to vaporize such liquid. So by therevolution ofthe shaft f, with its arms and the sponges thereof, withinthe liquid, more or less of the liquid will be taken up into theair-space ofthe vessel B, and by dripping from the sponges such liquidwill be more orless vaporized. The combined air and vapor may bedischarged from the vessel B by means of one or more pipes and led toburners, where it may be inflamed for the purpose ofobtaining light andheat by its conbustion.

In order to effect the vibratory movements of the scoop or bucket-shaftF and. to insure a rotary motion of the agitator or distributer K, Imake use of mechanism, which may thusbe described: On the outer end ofthe shaft f a gear, a, is fixed. This gear engages with another gear, k,carried by a shaft, 1, which is supported within a frame, m, arrangedbetween the two vesselsA. B. The shaft 1 carries a gear, m, whichengages with anotherbut by a pawl, q, and ratchet r is estopped fromrevolving in an opposite direction on the shaft. This enables the cordof the weight to be wound upon the barrel or pulley without producing arotary motion of the shaft 1. During a descent of the weight-the'sha-ftlwill be put in revolution, andthus a positive motion will be imparted tothe agitator as well as to the sponge-shaft. and arms within the tank orcistern B. On one end of the shaft 1 is a crank, s,'which, by means of aconnectingrod, t, and while in revolution, imparts a reciprocatingvibratory motion to a toothed rocker-sector, u, which en gages with apinion, 'v, fixed on the scoop-shaft F. Fig. 8 representsa side view ofthe crank s, the connecti ng-ro'd t, the rocker-sector u, and the pinionr, such being the mechanism by which the scoop-shaft F obi a-ins itsreciprocating motions duringand by the revolutions of the shaft 1.

With the vaporizing-cistern Band the mechanism for operating thescoop-shaft F, I have combined a mechanism for regulating the movements.of the scoops or the air-forcing apparatus to the required productionand consumption of carbureted air from time to time, the apparatusceasing to act during any excess of production and pressure of themixture of the air and vapor within the vessel B. The mechanism inquestion is. a friction-brake, to act against one side of therocker-sector u or to be forced against the same by the pressure an arm,2, which projects from a screw-shaft, I

in its outer surface, as seen in Fig. 9, such groove being made toreceive a stud or pin, 1), projecting from one of the shaft-bearings 0,(see Fig. 10,) which is a cross-section of the bearing and screw-shaft,

From the above it will be seen that during the vertical rise of the bell0 of the vaporizing cistern B, such bell will so move the lever 'w as tocause the screw-shaft to be forced'end. wise against the rocker-sectorin such manner as to roduce friction sufficient to overcome the tendencyof the weight suspended from the barrel 1) to revolve such barrel, inwhich case the scoop-shaft F, as well as the shaft), will have theirmotions arrested, and they will not be again put in movement until thepressure in the vaporizing-cistern may have diminished.

Having thus described my said improved apparatus for vaporizing ahydrocarbon and m'ixingair with the vapor thereof, what I claim thereinas of my invention. is as follows, vizr 1. The combination of one ormore air-cells and vibratory scoops or buckets, applied together andwithin the cistern A, substantially in manner and so as to operate.therewith as described. g r

2. The combination of the Barkers mill, or rotary air and agitatingdistribut'er K, with the vaporizing-cistern B, the cistern A, and itsair-forcing apparatus.

3. The combination and arrangement of the shaft F, its arms and spongesor their equivalents, with theagitating and air distributer' K, thecisterns A B, and the air-torcingapparatus of, the cistern A.

- 4. The combination of the friction-brake apparatus consisting of thelever to, the consubstantially as described, as well as its ar-vrangement with respect to the bell and the vibratory sector, asspecified.
